Title: Micrometric plane for cutting the reeds of wind instruments
Inventor: NEVEUX DANIEL
IPC: B23Q11/00
Filed: 1984-03-07
Abstract: The invention relates to a device allowing small pieces of reed to be brought to a thickness accurate to 1/100 mm in order to make double reeds for wind instruments therefrom. This device is composed, on the one hand, of a device 1 for fixing the small pieces of reed intended to be planed and, on the other hand, of a movable assembly 2 carrying a cutting blade 3 whose movement is perfectly guided on a rail 4 and by a shaft 5. The adjustment of the thickness of the chip is ensured by the rotation of the screw 6. The lateral positioning of the cutter with respect to the axis of the reed is ensured by the rotation of the drum 7 graduated in 1/100 of mm. The thickness of the reed to be produced is adjusted by means of the second drum 8, itself also graduated in 1/100 of mm. The entire assembly is securely fastened to a plate 9. The movement of the movable assembly is easily manually produced by means of the handle 10. In a few passes of planing perfectly calibrated reeds are obtained. The plane, whose dimensions can be adjusted to the manufacture of reeds for various wind instruments, is very easy to use and allows very precise adjustment of the thickness of the reeds.

Title: Automatic method of optical analysis and line-by-line electronic checking of the graphics of a two-dimensional scene, by tracking of shapes
IPC: G06T7/00
Filed: 1985-07-29
Abstract: The invention relates to a method of optical and electronic checking of the graphics of a scene by an absolute method. This method consists in carrying out acquisition, line-by-line, of linear images of the scene. Prior to the processing of each line, an electronic file of shapes Fj is memorised, representing previously-interceded shapes and their preceding evolution. This file of shapes Fj comprises tables of parameters linked to geometry, age and the width of the shapes being processed. At each line, an electronic numerical table of segments sj which are representative of the evolution of the shapes in the course of line lj is updated. From the shape file Fj and from the table of segments sj: - on the one hand, a new file of shapes Fj + 1 is defined on the basis of numerical rules for checking shapes; - and on the other hand, on the basis of rules for numerical monitoring of the change in shapes, the line faults alarms are updated. The rules for checking and monitoring the change of shapes is memorised in the form of a numerical table. The method of the invention has a particularly advantageous application in the field of automatic control of industrial products having high-density surface graphics such as printed circuits and integrated circuits.
